Question 45
PHMCQ2 marksNeeds review
A neutron beam with a wave vector
and an energy 20.4 meV diffracts from a crystal with an outgoing wave vector
. One of the diffraction peaks is observed for the reciprocal lattice vector
of magnitude
. What is the diffraction angle in degrees (rounded off to the nearest integer) that
makes with the plane? (Use mass of neutron =
Kg)Your answerChoose one option.
